The origins of the ancient Roman numeric system was based on a counting method using the fingers. A single pen stoke represented one finger and this translated to the number I. Additional letters were added to accommodate larger numbers. A "counting number," is also known as a Cardinal number that reflects a quantity. An Ordinal Number reflects words like "first", "second" or "third".
